SYNOPSIS:
Indian Railway is the largest railway system in the world under a single management
having 63000 route km, handling 14 million passengers per day and 1.8 MT freight
per day. Till recently, there was complete monopoly of the railway organization for
movement of freight and passenger traffic. But, due to development and
strengthening of road network and availability of better and improved road vehicles,
the roadways are not only offering stiff competition to the railways but are also
snatching away traffic from the railways. This, coupled with increasing
transportation requirement arising out of accelerated growth of the Indian Economy,
has forced Indian Railways to reorient itself and gear up for the challenges offered by
the present scenario. The Indian Railway needs to convert this challenge into an
opportunity and devise various means to meet the demand. As considerable growth in
freight movement is expected, it has become inescapable for Indian Railway to go for
freight trains with higher axle loads. An attempt is being made, through this paper to
study and evaluate the implications of Higher Axle Load (32.5 tonnes) and High
Speed ( 250 kmph.) on track ballast and sub-ballast and suggest the
specifications/requirements of the same.
